The invention relates to apparatus for pre-cleaning of gas and gas streams with high dust concentrations and can find prieneniyu as a first stage of cleaning in the aspiration systems of various industries and is an improvement of the auto-separator according to aut. No. 929166.

The purpose of the invention is to increase the separation efficiency and prevent the secondary discharge of pshi while increasing the gas load range and dust-gas flow rates while maintaining the size of the dust separator.

Figure 1 presents the scheme of the dust separator; figure 2 - node I in figure 1; on fig.Z - section aa in figure 1.

The inertia separator comprises a housing 1, the lower part of which is a dust bunker 2 for collecting the captured duster. An inlet 4 is attached to the side vertical wall 3 of the housing 1 for introducing a flow of filled gael, and an outlet of 6 is attached to the bracket 5 of the housing 1 for outputting the cleaned gas. The front and rear walls 7 of the housing 1 are arranged vertically, and the wall 8 located opposite the inlet 4 is inclined toward the hopper 2. The inclined wall 8 and the side wall 3 are connected by a shell (partition) 9 containing vertical plates 10 connected by a lid 11, made in the shape of a half cylinder. Cylindrical separation elements 12 are attached to the lower edges of the plates 10. The inner space of the shell 9 forms the chamber 13 of the burned gas, and the outer side of the shell 9, the walls 7 and the cover 5 form the chamber 14 of the cleaned gas.

Parallel to the inclined wall B opposite the inlet 4, there is a plate 15 made of a flake punch sieve having openings 16 with staggered edges 17 in a staggered order. Plate 15 and walls 8 form a channel 18 for dust discharge to the hopper 2.

Inertial tiller works as follows.

Due to the rarefaction created by the booster, the pie-gas flow through the nozzle 4 enters the chamber 13, where the main part of the flow

. hits the wall 8 and changes its direction, turning down towards the bunker 2. Next, the flow again changes its direction, divides into two parts and turns up, bending around the plate 10 and elements 12. The largest particles are drunk, continuing by inertia, they are separated at the first turn of the flow and, reaching the plate

15 to 15, pass into the openings 16 and through the channel 18 are removed into the hopper 2. The particles of medium dispersion are separated at the second turn of the flow relative to the plates 10 and the elements 12.

20 At the same time, depending on the size of the particles, the radius of the elements 12 is selected. The separated particles are separated from the gas flow into the hopper 2, and the purified gas,

A passage 25 through chamber 14 is expelled from the apparatus through the outlet 6. I

Thus, the separation of drunk

3Q occurs both in the zone bounded by the inclined wall 8 and the chamber 13, and by splitting and rotating the pie-gas flow relative to the elements 12 and the plates 10. Such a constructive solution allows to isolate the separation zone from the impact of the suction flow at the outlet of the apparatus, to exclude the intersection of the separated flows dust by the gas flow and the possibility of secondary entrainment of the drone; to ensure an organized diversion into the bunker of the drunk that was trashed on the first turn of the stream through 90, to organize the second turn of the stream above the bunker up when the main stream is divided into two parts and the flow around them of separation elements installed above the bunker, in a plane perpendicular to the plane of the primary turn of the stream.

This increases the efficiency of trapping the flume with an increase in the speed of the air flow, which allows a large unit to be created; 55 productivity of the gas to be cleaned without reducing the cleaning efficiency and increasing the size.

The use of this dust separator as a first stage of purification allows to increase the degree of air purification from dust, to prevent the formation of dust deposits in airflow systems, to reduce dust loads on devices of subsequent stages of purification and, consequently, to reduce pollution of the atmosphere.
